[ Upstream commit 8c2ae772fe08e33f3d7a83849e85539320701abd ]
In __spi_pump_transfer_message(), the message was not finalized in the first error return as it is in the other error return paths. Not finalizing the message could cause anything waiting on the message to complete to hang forever.
This adds the missing call to spi_finalize_current_message().
